Included in this paper is an outline for the book "Multiculturalism in the Mainstream: Teacher Researchers Build Multiethnic Literacy Communities in Urban Multicultural English and Social Studies Classrooms." The paper presents full descriptions of the chapters; a draft of the first chapter; a draft of a completed teachers' chapter; and a sample of an approach to creating multiauthored teacher chapters, which will be used in the final draft as a way of consolidating a number of the proposed individual teachers' chapters as well as the work of teacher participants not represented in the book outline. The editors of the book outlined in the paper plan to use this multiauthoring as a way to highlight key themes that are prevalent across all sites. Although the sample multiauthored chapter focuses on one site only and on the issues of doing teacher research rather than on teaching and learning in multicultural settings, the multiauthored chapters in the book outlined in the paper will span the four sites and will focus on the issues that are focal to the teachers' research.
